Field Data Collection Collect new information Utilise pre-prepared menus, hand held devices, satellite imagery and other digital maps and local counterparts Data Collection Issues Natural hazards: Cyclone Pat, Aitutaki Cook Islands, Cyclone Ulia Solomon Islands, 3 erupting volcanoes in Vanuatu Inconsistent assistance from local counterparts Reluctance of Gov t departments to give access to data Poor georeferenced imagery/lack of control points Ill health/disease Dogs Vehicle difficulties poor roads Suspicious people 3

Next steps Complete field work in each country Establish databases in each country identify where and how to share, delivery and maintenance mechanisms. Training and data support in each country Issues Assumptions that all stakeholders in-country are informed Finding the right in-country organisation to collaborate with (not finance) Short timeframe Obtaining data from government departments Being unaware of other similar in-country or donor activities No high resolution DEM s available Poor georeferencing of imagery Dated imagery Few geology, soil and hazard maps For the data to be useful beyond catastrophic finance requires hazard maps. 7
